METAL SI'mET-PILING (JUNCTION UNIT).

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed March 28, 1908. Serial No. 423,837.

To all whom it may concern: l

Be it known that I, MARLEY W. CLUx'roN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Sheet-Filing, (Junction Unitg) and I do hereby declare that the' following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

This invention relates to improvements in interlocking metal sheet piling and refers more specifically to improvements designed to Jfacilitate the joining of meeting or intersecting walls made or constructed of such piling.

The invention consists in the matters heref l inafter set forth and more particularly point-A ed out in the appended claims.

My improvements are more specifically adapted to that form of metal sheet piling wherein a wall composed of such piling comprises alternate simple and compound sections which have interlocking connection at their margins. A. concrete example of such piling heretofore devised embraces I-beams for the simple sections and oppositely arranged, rigidly connected channel bars for the compound sections, the flanges of which are directed towards each other but separated a distance to receive the webs of the I- beams, with the flanges of said beams and bars interlocked with each other.

In the drawings Figure 1 is a fragmentary perspective view of the upper ends of the metal sheet piling arranged to constitute two meeting walls, showing my improved means for connecting the same. Fig. 2 is a partial plan view and a partial horizontal section thereof. Fig. 3 is a partial plan view and a partial horizontal section, showing a slight modification.

As shown in the drawings, 10, designate the simple units and 11,11 the compound units of the metal sheet piling. The said simple units comprise, as herein shown, I- beams, the oppositely extending marginal flanges 12, 12 of which have laterally inter locking and longitudinally sliding engage ment with the compound units. The compound units each comprises two laterally separated, rigidly connected rolled shapes 14, 14 provided at their margins with right angle flanges 16, 17, the two flanges at each edge of the compound units being directed toward eachother, but terminating such distance apart as to receive between them the webs of the I-beam units, with the flanges thereof interlocking with the flanges of the members of the compound units. Throughout the length of a wall composed of said units, except at the junction thereof with a transverse wall, the said members of the compound units may consist of plain channel bars, or the units at the sides of said junctions may be otherwise formed or arranged for interlocking connection. One or both of the members of the compound unit located at the junction of a main wall with a transverse wall is, however, of special form to constitute a junction connection, as will hereinafter appear.

In accordance with my invention, the junction of a main wall with a transverse meeting wall occurs in line with a compound unit of said main wall. One of the side members of the compound unit of a main wall at the junction thereof with a transverse wall is formed to provide on the outer side face of said member adjacent to the transverse wall with a vertical groove to receive the flanges 12 of the simple unit of the transverse meeting wall. If the main wall is to be joined with a transverse meeting wall alt one side only, the compound junction unit of the main wall is provided at one side only with such vertical groove. If, however, the main wall is to be joined to two oppositely extending transverse walls,

then both members of the compound junc tion unit will be provided with said vertical grooves for interlocking connection with the said simple units of the transverse walls.

As shown in Figs. l and 2, provision is made for connecting a transverse wall with one side only of the main wall. In this event one side or member of the compound junction unit of the main wall may consist of a plain channel bar 14. The other side or member of said junction unit is shown as consisting of an I-beam, two of the flanges 17, 17 of which are parallel with and directed towards the flanges 16, 16 of the channel bar 14. The opposite flanges 18, 18 of said I-beam member are bent or folded inwardly towards the web of said member so as to form between said web and the inwardly folded flanges grooves to receive the fianges 12 of the I-beam or simple unit of the transverse meeting wall. The said IOO llt)

' 'The 'said lateral y the 'said members a fixed 'by "means of bolts 'j versely through the l5 groove thus formed affords guidingandlocking engagement between the junction unit` and the simple unit of the transverse meet ing wall, permitting ,one unit from the other when being driven in the .samelmanner as the vsimple ,and compound units of the usual construction are guided c* one from the other while being driven', and also affording means to interlocktlie junction units to the other' units of the wall.

members of the compound units"` are fastened rigidly together '19,V 19 extending transing'sleeves 20, QOVvwhich surround said bolts and bear sides of the members. of the compound units. Said spacing sleeves serve to space or hold distance apart, and

saidV members are held from spreading by l' the heads and nuts of said bolts; The bolts also serve to greatly strengthen the compound units. VThe heads of the bolts 19 are countersunk 'in the web of the Ir-beam mem-A ber of said junction unitso as'to afford a plain or non-projecting exterior face on the side of the unit adjacent to the transverse ,Y jwall for k.engagement with the flanged fmarf gint-ofv 4the vision is madefor extending transverse adjacent simple or VI-beam y unit inwardly from the yinterlocking rguide the units while ,being 1f yInthe construction shown in Fig. 3, kprojoining two oppositely walls. toa single juncwebs thereof, and spac! at their ends against the .innervr andvto hold said units rigto be guided 1 use of sheet referred to sonef'of' the y for convenienceof yare located. at suche tiOIlvlllitoffthemain wall.- In this construction, thejtwo members 25,-. 25` lofthe ,'compound ljunctionunit consist :of I-beams,

The .4 outer flanges 27, 27. of said Ifbjeam members towards the webs. of said lmembers to provide .verticalgrooves at both sides.l of Asaid unit togreceive the simpley orfI-beam units. yIn the latter Qoiistructionthetwo members of the comlfgound junction j unit `are. fastened together 4rivets 28,228, thev heads of which are AVcoiintersunk inthewebs of saidside Lmemubersjso as to provide l said members fors/engagementk with` the nieeting'walls may occur atthe corner of Yan :inclosing wall vmade up ofthe metal piling xklescribed,A or .mayoccur at any pointer PQHS in the, length, ofthe Wall.

' The construction described vradords an eX- ceedingly simple and effective means of joining two meeting metal sheet piling walls and avoids the necessity of providing a special junction fittingat the intersection of the walls as hasheretofore been common in the piling of the construction herein shown. Moreover, the junction ofa meeting Y wall with the compound or stronger unit of a main wall is Vadvantageous inasmuch as it provides great strength and durability at the j unctionor meetingpoint.vr I haveyherein walls as amain wall description onlyfandit will beunderstood thateither' of two meetingwalls thus joined maybe regardedas the main wall.

I claim as myv invention 1l Inlinterlocking sheetmetal piling, a,

junction-unit for joining ajmain wall to a transverse wall, said junction unit comprisingtwo laterally separated members having at their margins flanges turned towardeach other kto interlock with flanges of adjacent units ofthe main wall, one of the members of said munit having at its-margins other flanges `turned toward each other toy interlock with the anges of an adjacent unit of the Vtransverse wall.
